Hi Mari
Glad to see you made it to the forum...this is a great place to start your search. I'm only sorry we don't have the perfect little girl available for you right now.
We met Mari and her husband this weekend at the show in Minnesota and she comes with excellent references from other breeders at the show. If anyone would like to PM me feel free, she seems like a lovely lady and she lives right down the road!
Most of the breeders will have screened their adults before they ever think of breeding them. They will have patellas certified and done Bile acid testing.. some also do liver function on the pups prior to placement as well as the vet checks and the health guarantee.
There are some wonderful Biewer breeders here, it may take a bit of patients to find just the perfect fit but it will sooo be worth the wait.
My advice is to read all you can on the breed, find some lines you like, talk to some breeders and wait.. that perfect little girl will eventually pop her pretty little head up in search of her new mommy.
Best of Luck in your search.. I'll keep my eyes open.
